If the display console does not connect within the first 5 minutes, ref er to the following section, “RE-PAIRING SENSOR”. You will see the icon of an antenna scrolling in the temperature and humidity (outdoor) section of the display. Once the pairing process completes, the antenna icon will appear solid (not flashing), and the readings for outdoor temperature and humidity, wind speed, wind direction, UV, light intensity, and rainfall will appear in their designated sections of the LCD display. ● ● ● ● RE-PAIRING SENSOR If the connection fails or the display console is reset, then press and hold the 【CHANNEL】button over 2 seconds to enter pairing mode, and the display console will re-register all the sensors that have already been registered to it befor e, (i.e. the display console will not lose the connection of the sensors that you’d paired up befor e.) 17 Model number: Main Features: YT60245 Outdoor temperature/humidity reading, weather index Wind direc�on & speed Indoor temperature/humidity reading Weather forecast Time & date, moon phas e, Weekday Light intensity UV in dex Rain Baro meter WI-FI CONNECTION STATUS When the display console successfully connects to your Wi-Fi router, the Wi-Fi signal will appear on the LCD display. If the Wi-Fi signal is not stable or the display console is trying to connect to the router, the icon will flash. If the icon disappeared, it means the display console is not connected to the Wi-Fi router. TIME SERVER CONNECTION STATUS After the display console has connected to the internet, it will attempt to connect to the internet time server to obtain the UTC time. Once the connection succeeds and the display console’s time has updated. The icon “SYNC” will appear on the LCD. To display the correct time for your specific time zone, you will need to change the time zone in the CLOCK setting mode from 00 to your time zone (eg.GMT+1). If you don’t know your time zone, you can look it up online.
